Definitions

  • FIG. 1 is a schematic partial sectional view of a clutch device according to an embodiment.
  • FIG. 2 is a front and partial sectional view of a clutch device in which a torque variation absorber device according to an embodiment is provided.
  • FIG. 8 represents a modification of a torque variation absorber device.
  • Clutch device 1 includes a flywheel 62 .
  • Flywheel 62 is formed in a disk shape, having an engine shaft 93 inserted through its center to be secured. Flywheel 62 is formed in a rotatable manner.
  • Engine shaft 93 functions to output the rotation force of the engine. The rotation force of the engine is transmitted to flywheel 62 via engine shaft 93 .
  • Pressure plate 90 according to the present embodiment is formed in an annular shape. Pressure plate 90 is formed to push clutch disc 5 toward flywheel 62 through a uniform force. The face of pressure plate 90 in contact with clutch disc 5 is formed flat.
  • a diaphragm spring 70 is a biasing member to push clutch disc 5 against flywheel 62 via pressure plate 90 .
  • Diaphragm spring 70 is a clutch spring. Pressure plate 90 is pushed toward clutch disc 5 by diaphragm spring 70 .
  • Coil spring 4 is assembled in a manner similar to that of coil spring 3 . Therefore, detailed decryption thereof will not be repeated.
  • Predetermined distance ⁇ L is set such that the abutting state between the components of coil springs 3 , 4 , support member 6 , 7 , spring sheets 8 , 9 , cam member 11 and arm members 20 , 40 is maintained when the amount of deviation between the center of rotation of cam member 11 and the center of rotation of disc plate 30 takes an upper limit.
  • the center of rotation of cam member 11 at the second initial position is deviated towards the side of one end section 22 of arm member 20 relative to the center of rotation of disc plate 30 .
  • One end section 22 of arm member 20 is located at the outer circumferential side of disc plate 30 than the location of one end section 22 when the initial position of cam member 11 is the first initial position at disc plate 30 .
  • the other end section 26 of arm member 20 is located moved in the direction of compressing coil spring 3 than the location of the other end section 26 when the initial position of the cam member is the first initial position.
  • the length of coil spring 3 is shorter than the length of coil spring 4 . Therefore, when the initial position of cam member 11 is the second initial position, the resilient force imparted to cam member 11 from coil spring 3 via arm member 20 becomes greater than the resilient force imparted to cam member 11 from coil spring 4 via arm member 40 , as shown by the arrow in FIG. 6 .
  • cam member 11 When the initial position of cam member 11 is the second initial position, there is a difference between the resilient force acting on cam member 11 from coil spring 3 and the resilient force acting on cam member 11 from coil spring 4 even if the torsion angle is identical corresponding to the deviation amount of the center of rotation as compared to the case where the initial position is the first initial position.
  • the present invention is not limited to the provision of a resilient member at both the inner circumferential face of disc plate 30 and the outer circumferential face of boss member 12 shown in FIG. 8 .
  • a resilient member may be provided at only one of the inner circumferential face of disc plate 30 and the outer circumferential face of boss member 12 .
